John:  My Webster's New World Dictionary states that the synonym for
extirpate is exterminate.  Under exterminate, it states...SYN.- exterminate
implies the complete, wholesale destruction of living beings or things whose
existence is considered undesirable; extirpate and eradicate both suggest
the extinction or abolition of something, extirpate implying a deliberate
and violent destruction at the very source so that the thing cannot be
regenerated, and eradicate connoting less violence and often, the working of
natural processesor a methodical plan.
So I have to maintain that unless someone went to Streetboro Fen to
deliberately snuff out the Mitchell's satyr, it was not an extirpation.
That habitat destruction resulted in its vanishing from the site-- I would
agree on that.
